Information about Uzhydromet
The Centre of Hydrometeorological Service at
Cabinet of Ministers of the Republic of Uzbekistan
(Uzhydromet) is the state governing body specially
authorized for the solution of tasks in the field of
hydrometeorology in the Republic of Uzbekistan.
The objectives of Uzhydromet are the development
and improvement of the state system of hydrometeorological
observations, hydrometeorological provision of the sectors of
economy, scientific research activities, improvement of shortterm and long-term weather forecasts, water availability of
rivers, climate change.
Structure of Uzhydromet
The network united under Uzhydromet includes more than
400 environment observation stations including hydrological,
meteorological, agriculture, and agrimeteorological stations. These
observations are carried out on the territory of republic since 1921. The
ecological observations of the conditions of water bodies, air and soil are
carried out since 1972.
The Meteorological network of Uzhydromet consists of
79 stations. The observations are conducted by programme M-1 (1st
grade weather station) at one of them. On 78 weather stations the
operations are conducted by programme M-II (2nd grade weather
station). All of 79 stations are operating in traditional mode. The
automatic weather station is operated only at Chimgan snow avalanche
station. 19 stations of 79 are stations of international exchange, 8 of
them are stations of exchange of hydrometeorological information with
CIS countries.
The Uzhydromet and WMO
The Uzhydromet actively participates in international activities
of the Republic. In 1993 Uzbekistan acceded to Convention of the World
Meteorological Organization and actively participates in implementation
of all WMO Programmes.
Uzhydromet is the component of one of UN links – World
Meteorological Organization (WМО), the main aim of which is weather
and climate observation, cooperation for collection and exchange of
data of meteorological, hydrological and other observations of
environment conditions.
Uzhydromet annually gets free costly information (upper-air
data, various weather maps, actual weather data and short-term
forecast over foreign airports, synoptic information, satellite data) from
the world's leading meteorological centers, from satellites, which is
necessary for the hydrometeorological provision of the country
economy.
The Uzhydromet and WMO
Recently with the assistance of WMO and
international organizations, the instrument pool of the
hydrometeorological service is partially modernized.
With the assistance of the government the upgrading
of remote sensing equipment was carried out for Doppler
weather radars with special software, which is a structure
of technical, information means and technologies.
Weather Radars
Meteor-500 Doppler weather
radar of "Selex" company
VHDD-350C Doppler weather
radar of "Baron" firm
Weather Radars
VHDD-350C Doppler weather radar of
"Baron" firm
VHDD-350C meteorological radars
installed in the cities of Tashkent and Nukus
are designed for detection of the severe
weather phenomena associated with
cloudiness (hail, storm, heavy shower, squall,
long and intensive continuous precipitation,
turbulence) in a radius of 240 km and
operating at frequency from 5.4 to 5.9 GHz,
for meteorological provision of aircraft
operations and solving of task of informing the
relevant authorities, agencies, as well as
population of the Republic of Uzbekistan about
severe weather events.
Weather Radars
Meteor-500 Doppler weather radar of
"Selex" company
Meteorological radar Meteor-500 installed in
Samarkand is similar to "Baron" system an в is
also designed for detection of severe weather
phenomena associated with cloudiness (hail,
storm, heavy shower, squall, long and intensive
continuous precipitation, turbulence) in a radius
up to 250 km and operating at frequency of 5.4
to 5.6GHz, as well as for meteorological
provision of aircraft operations and solution of
task of informing the relevant authorities,
agencies, as well as the population of the
Republic of Uzbekistan about severe weather
events.
Weather Radars
Installation and operation of weather radars can provide for:
1
2
3
4
5
Receiving and display of space patterns of cloud and precipitation fields at
the maps of the regions
Producing of maps of hazardous weather phenomena (squall, thunder
storm, hail, heavy rainfall) over a map of the region.
Tracking of the evolution of cloud structures and determination of the direction and
speed of movement of clouds of the cloud systems and hazardous weather
phenomena
Calculations and display of maps, intensity and amount of precipitation in
the region
Calculations and display of maps, intensity and amount of precipitation in
the region
Weather Radars
Thus the usage of automated systems and radars
allows the objective assessment of the state of the atmospheric
phenomena and provision of the weather forecasts.
In the nearest future the further modernization of
meteorological stations in the WMO synoptic system is being
planned.
Aeronautical Meteorological
Station
KRAMS-4 Aeronautical Meteorological Station of civil aviation of
"VAISALA" firm
The equipment of aeronautical meteorological stations
of civil aviation is completely updated with the
equipment such as KRAMS-4 of "VAISALA" firm
designed for measuring and collection of information
about the basic parameters of the atmosphere at the
airport, processing this information, formation of
meteorological messages, display of this information,
recording and dissemination of information through the
communication channels for providing the safety of
takeoff and landing for aircrafts.
Aeronautical Meteorological
Station
AMIIS - 2000 Airport meteorological System
Airport meteorological information-andmeasurement AMIIS-2000 system is designed for
collection and processing of meteorological
information on the basic parameters of the
atmosphere in the airport area, the formation of
meteorological messages, displaying, recording and
distributing of metadata through communication
channels to ensure the take-off and landing of
aircrafts.
Satellite technologies
System of receiving and processing of satellite and meteorological
data of China Meteorological Administration CMACast
Satellite technologies
Tasks:
1
Keeping 24-hour processing and receiving of satellite and
meteorological data
2
Analysis and forecasting of synoptic processes and
associated weather conditions in Central Asia
3
Forecasting of movement and development of
cloud formations
4
Development and implementation of new methods
for subject processing, keeping the archive
Satellite technologies
Satellite data receiving system of MODIS (Terra and Aqua)
The satellite system allows using the data received from Terra and
Aqua satellites in different areas of economical activity:
Operational assessment of the ice cover and snow cover.
Early detection and monitoring of the development of the forest and
grassland fires, dust storms.
A wide range of combination of parameters of the offered data types
(spatial resolution, swath, spectral domain), frequent repetition of
shooting (1-2 times a day).
Besides, the received information allows to organize monitoring of
farm lands, both in terms of compliance with the rules of crop rotation
and from the point of view of the target land use, to conduct an
operational assessment of the condition and the extent of degradation
of agricultural and grazing lands.
Satellite technologies
Tasks of that system are:
An inventory of agricultural
lands, crop condition
monitoring.
Identification of areas of
erosion, salinization and
desertification.
Monitoring of the quality and
timeliness of the various
agricultural activities.
Monitoring of development of
the agricultural crops and crop
estimation.
Conclusion
The significant growth of computer technology, various
telecommunications means can meet the challenges of consolidation and the
integrated usage of various instruments, radar equipment for solution of the
issues of tracking, short-term forecasting and modification of weather
phenomena at the new level.
The enhancing the functionality of existing technology allows to:
Improve the efficiency, accuracy and reliability of
weather information.
Improve the quality and timeliness of managerial
solutions by conducting the activities on the work
modification.
Provide the meteorological information to various
customers concerned.
We appreciate the CIMO’s leading role on WIGOS to further promote
WMO Members national observing capability
